between the upper and lower chucks. After for said seeming tools, and means for inde the seeming operation is completed when the shaft or spindle of the lower chuck is again lowered,` the two members of the friction clutch arr separated when the chuck B en gages its stationary rest or support l). lThe lower chuck spindle or shaft C is driven from the main driving shaft G, preferably through a pulley g on the driving shaft, belt g1 passing over idlers g2 end e pnlley'C on the shaft C.

The shaft C of the lower chuck may be reciproceted in its bearings on the stationary frame of the machineby any suitable means. Ipreferably employee treadle C2, connecting rod (Pfand lever or rock shaft C1 for this purpose, the seme being returned to position by a s ring C5.

4 he shaft E1 of the upper chuck` E is rotated or driven by a bevel gear E2 thereon, meshing with e bevel gear E3 on the driving shaft G.

The tool holders F2 F3 are moved or reciprocated es required preferably by means of cams h h1 on the cam shaft H which engage enti-friction rollers lfon the tool holders. The cam sheft H is intermittently operated or rotated es required from the drivin shaft G referebly by a pulley g3 thereon, be. t gi, puiey gs on shaft g which is .provided with a Worm g7 en aging the worm gear h2 on the cani shaft The cem shaft H is with e, stop cam h3, engaging the ro ler K on the crank erm K1 which is pivoted at 7c to the sliding frame M, seid frame being operated by' the screw M1, for cans of various diem* eters. Pivoted to the arm K1 at k1 is a connecti rod R connected to the lever or rock shaft Through this connection the mechine may be started by the downward movement of the hand loyer 7cZ on the crank erm K1. The crank erm also has a lug 7c3, a connecting link lc* pivoted at one end to the lug k and et the other end to a pair of rocking links k, said rocking links rocking on the pivot k and connected at their other end to the clutch shifter S.

The tool holder F3 for the closing or finish.w

-ing seeming roller F1, is preferably furnished with e supplemental part F* carrying en anti-friction roller f and slidahly connected' with the main portion F3 of the tool holder, end With e spring F5 inte osed between said parts F3 an F4 to give t e seeming tool F1 e `cushioning oryiel 'ng pressure against the seam and thus enable 1t to accommodate itself to the side seem of the can body. An adjusting screw F" limits the slidin movement of the two parts of the tool hol er F3 F4 in respect to each other and also regulates .the tension of the's rin The part F4 of the tool holder has a' ug 7 through which the ediusting screw F6 slidably extends.

l. in e seeming machine, the combination. with the seeming tools, independent holders rovided pendently operating said seeming tool holders, ol' n. pair of rotary can holding chucks, and a positively rotating shaft and a clutch interposed between one of said can holding chucks and said shaft for rotating it, and ineens for reciprocating one ol' said chucks, substantially as specified.

Z.Y ln a seeming machine, the combination with a seeming tool, a removable holder for said seeming tool and means for operating said tool holder, of a rotary can holding chuckfa rotatable and reciprocating can holding chuck, a reciprocating and )ositively rotating shaft ors indle for said chuck and a clutch interpose between said rotatable and reciprocating can holding chuck and the shaft or spindle for operating it, subn stantially as specified.

In a can seeming machine, the combinetion-With e seeming tool, of en upper rotely can holding chuck, e lower rotary and reciprocating cen 'holding chuck, a shaft or spindle therefor, a stationary rest or, su port for said lower chuck, e friction clutcli beu tween said lower chuck and its shaft, means for continuously rotating the up er chuck, means fr continuously rotating t e shaft or spindle of the lower chuck, and means tor operating'the seeming tools, substantially' es specified.

7. In a seeming machine, the combination with the seeming tool. ef a rotary can hplding chuck, an opne` rotary endreciprocating can holding chuck, and mechanism for rotating and rcciprocetinfy said last nientioned chuck, provided with means for causing the cover to be clamped on the can body before the chucks impart a rapid rotary movement to the can, said means comprisin s clutch lnterposed between -therotary en l reciprocating chuck and its operating shaft,

vclniclr, s rotatable' and recipoccting can hol chuck, a reciprocating s aft or spindle for sai chuck, a clutch and a stationary rest or support engaging said .rotary and reciprocating chucl; w en retracted, substantially as specied.

9. ln a, can seeming machine, the combineltion with a seeming tool, of an upper rotary can holding chuck, s lower rotaryv and reciprocating can holding chuck, a shaft or spindle therefor', a stationary rest orsupport for said lower chuck and a clutch between said lower chuckv and its shaft, substantially as specified.

10. In a can seeming machine, the combination with a seeming tool, of an upper ro te reiirocating can'holdingchuck, a shaft or spindle therefor, a stationary rest o'r support for said lower chuck, a clutch between said I lower chuck and its shaft, means for continuously rotating the upper chuck, an'd means for continuously rotating the shaft or can holding chuck, a lower rotary and.v
